This may seem kinda sad but if they use this without checking they deserve it!
The concept of reCAPTCHA is a noble one: it utilises a CAPTCHA system of word verification to not only verify a human is there but to also help digitise text.
Now the fun part is to screw with that. After playing around with the form a few times it becomes mostly apparent which word is generated and which comes from a scanned book. I simply replace the word from the scanned book with the word "penis" and presto, one vote towards the word being "penis".
There are other sites using this CAPTCHA system, I first tried this on Facebook.
